Buoy: Marine Star-F Model SV-6000ES

Ship Station: Example of display of buoy and schooling fish information on chart
Features
By providing data on fish schools near the buoy, it facilitates the development of fishing plans. As a result, this leads to reductions in fuel costs, fishing fees, and other expenses.
The buoy has a built-in transducer, which helps prevent the buildup of shellfish and seaweed.
- You can estimate the size of a school of fish.
- Since you can view a history of fish school data, trends in fish school abundance are immediately apparent.
- It is possible to seamlessly share real-time location and fish school data with sister ships.
- The system automatically transmits fish school data every day at sunrise (sending 24 hours of hourly collected data in a single batch)
- You can inspect fish school details in the clearest, most optimal state using the GAIN (sensitivity) adjustment function.
- The buoy response time has been dramatically shortened compared to our conventional models.
- Water temperature is displayed in increments of 0.1 °C.
- It features a distance calculation function that calculates the total distance between multiple locations and estimated arrival times.

Echo Sounder System
Since data is transmitted and received via satellite communications, buoy information can be reliably obtained.
Buoy data and control commands from ship stations are transmitted via Inmarsat satellites → ground stations → Inmarsat satellites.

Data Collection Timing
The system automatically transmits fish school data every day at sunrise (sending 24 hours of hourly collected data in a single batch)
Data Transmission
Once the sun rises in the buoy’s area, all accumulated data is dispatched instantly as a single batch.
Customizing Settings
You can easily change the transmission intervals by sending a command to the buoy.
Choose from the following transmission modes to fit your needs: [Real-Time/Current, Every 10 Mins, Hourly, Every 3 Hours, Every 6 Hours, or Default].
In Default Mode, the 24 hourly logs are compiled and transmitted at sunrise.
Usability
The user-friendly ship station display software (BMOP, Buoy-MAX Operation Plotter) allows for intuitive, stress-free operation of buoys equipped with fish school information.
Conventional buoys can also be used simultaneously.
Past data is organized into clean lists, making comparative analysis effortless.
With the introduction of the Inmarsat IDP system, buoy response time has been reduced to within 3 minutes.
The positional information accuracy of the buoy has been enhanced down to 1/100 of a second.
The buoy’s battery voltage is displayed directly, allowing you to see the remaining charge at a glance.

Buoy Body
Housing of the SV-1800A type with enough results is adopted for buoy Shellfish and seaweed become hard to attach with the structure of the inner Hull method that a transducer does not go out.
Other Functions
Useless cost and waste of the time disappear by a theft alert function.
In the case of a desktop PC, buoy position data can be output to MAXSEA, Google Earth.
